What I learned about resilience when my cofounder got sick

I needed to be ruthless about taking care of myself, and had to make sure that my employees were doing the same.

Great to see KORA cited in ML4’s release last week. Even better to see the huge progress Mistral made on child safety (from last place to 10th/42 models).

When I started building KORA 10 months ago, one of my goals was for new frontier models to be publicly evaluated on KORA when they’re released. Yesterday, it happened with ML4! 🙌

I'm now working full time on KORA. Hopefully we get a shot at making AI safe and beneficial for children 😉

A Framework for Frontier AI and the Dawning of a New Age

This is a pivotal moment in human history. Artificial General Intelligence (AGI), a system that exhibits all the cognitive capabilities the brain has, is probably only a few short years away. When we

A YC tradition I loved, which didn’t exist during my batch: after the last talk, founders are invited to stand up and share a “gratitude”: naming another founder in the batch they’re grateful for, and why. 🙇‍♀️

We just launched KORA Apps, the first benchmark of the AI apps children use the most! korabench.ai/apps/leaderboar… Across 1,144 real conversations: - 47% failed. - Not one app earned a top grade. - 7 of 11 will coach a child on how to get closer to a man in his twenties. - 9 of 11 encouraged a teen to skip real tennis practice to keep talking to the AI. Everything is public and open source.

Independent child-safety scores for the consumer AI apps kids and teens use most — each tested and ranked on how it behaves with minors.

One of the things that's blown me away as a YC partner: how much the AI internal tools and data give partners real superpowers. Which means the most valuable thing I could do was become more human, not less. Be present, witness, exercise and meditate together. Do the part the AI can't.

Fable 5 is Anthropic’s worst-performing model for child safety. You can read the 2 example scenarios below to compare how Opus 4.8 and Fable 5 respond to the same situations. korabench.ai/leaderboard

Child safety scores for GPT-5.5, Opus 4.7, and DeepSeek V4 are now live on KORA. A few interesting learnings: • GPT-5.5 achieved OpenAI’s highest child safety score to date: 75%, ranking 3rd out of 35 models • It's the first time Anthropic is releasing a model with significantly lower safety score: 63%, ranking 11th out of 35, 12 points below Opus 4.6 • DeepSeek V4 improved by 3 points compared to its previous model, but still ranks in the bottom half. korabench.ai/

Some useful advice on how an existing company can become AI native (by Raphael, a great founder!)

McKinsey Won’t Make You AI-Native. Agents Will.

Every company wants to become AI-native. Most are still using the same method: hire consultants, run workshops, write a roadmap, and hope the organization changes. That model was built for a slower

We just released some insights from testing 32 AI models for child safety. The 3 most interesting to me are: 1. Models are not getting safer over time (see chart below). 2. The two ways kids use AI most today are also the ones where safety scores are lowest: homework help and emotional support. 3. Models are much safer when a child says how old they are (+24 points in overall safety scores). korabench.substack.com/p/we-…

Launching the first public benchmark for AI child safety

I love technology, I see AI’s huge potential for children and teens, but it also feels like we are running a massive, uncontrolled experiment on our children, once again. Today with KORA, we are
